Bitumen membrane is waterproof rollable sheet-like material in the base tire (such as paper, fabric) on the dip after bitumen membrane, and then the surface of the spreading powder or tablet made of insulating material. Refers to the role of water in the water infiltration and water after being unchanged the performance tpo waterproofing membrane, with no water permeability, commonly impermeability, water absorption and other indicators showing the action of water under pressure. Waterproofing membrane performance: 1. Water and water-resistance means that under the action of water infiltration and water after being unchanged the performance polyethylene fiber waterproofing membrane, SBS waterproofing membrane having impermeability under pressure water, commonly used impermeability, water absorption and other indicators showing. 2. Temperature stability at high temperature stability refers not flowing, no blistering, no sliding, low temperature embrittlement of performance, that is the ability to maintain the original performance at a certain temperature. Common heat resistance, heat resistance and other indicators showing. Polyethylene polyester waterproofing membrane, waterproof Yue-kun (certified), Shanghai waterproofing membrane provided by the Weifang City waterproof material Ltd. Yue-kun.
